Buyer support
Compare factory quotes for the same storage specification, quantity and destination.
Eligible coordination may include up to 3%.
Eligibility applies to qualified business buyers and is confirmed after we review your product, quantity, destination, and sourcing requirements.
Prepare specification, quantity and destination before you request factory quotes.
Application to purchase fields
Battery energy storage system suppliers can only be compared after the site job is translated into ratings, interfaces and a destination. EverCore Procurement writes that translation with the buyer. It does not certify the result.
Five situations change the interface questions. None of them is a performance claim for a named supplier.
Application: storage beside an operating building load. Interface question: whether the offer is AC-coupled at the existing switchboard, and what fault-current data the supplier still needs from the buyer.
RFQ unit: one building system. PV modules stay off this line unless the buyer adds them.
Application: a ground-mount plant that may share a collector with storage. Interface question: DC voltage of the array versus the storage input, and whether DC-coupled conversion is in the request at all.
RFQ unit: container count, with medium-voltage equipment named as a different package.
Application: power and energy requested for market or backup duty without a paired generator of PV. Interface question: grid-forming inverter behavior versus grid-following, as the supplier will document it.
RFQ unit: rated kW and usable kWh on separate rows.
Application: a buffer for fleet charging peaks. Interface question: the duty cycle across a shift, and which signals must pass to the depot energy controller. Charger connectors are not assumed to be part of the battery offer.
RFQ unit: depot storage system, chargers excluded until written in.
Application: several buildings sharing one storage yard. Interface question: how the energy management system selects loads, and which party configures it after delivery.
RFQ unit: yard equipment. Controls software is a separate confirmation.
An AC-coupled arrangement can suit a retrofit where PV already has its own inverters and storage is added at the AC bus. A DC-coupled arrangement can reduce a conversion stage on a new plant only when the voltages and the power electronics actually match. EverCore Procurement records which architecture the buyer is asking about. It does not choose one, and it does not treat a supplier slide as project approval.
For either architecture, request rated power in kW, usable capacity in kWh, the DC voltage window in V, continuous current in A, operating temperature in °C and round-trip efficiency with its measurement boundary. Ask whether cooling and other auxiliary loads are included, and request the depth of discharge, temperature and cycling basis behind cycle life. Record enclosure rating and thermal management separately from energy and power so a site condition cannot disappear into a headline rating.
A lower unit price may be usable when the buyer already supplies site controls and local service; a wider delivered package may be preferable when those responsibilities still need an owner. Compare equipment, freight, duties, spares, warranty and commissioning exclusions at the same quantity and US destination. Any sample or pilot should use an agreed review plan: match labels and drawings to the quoted model, record the ambient and operating conditions, and have qualified parties verify control interfaces against written acceptance criteria. Store the results and unresolved deviations before an award decision.
The US Department of Energy's Solar-Plus-Storage 101 (March 11, 2019) explains power versus energy and AC/DC coupling. Its historical project costs are not current supplier prices or evidence of this service's savings; use current model documents and project review for an actual purchase.
See inquiry labels, the checklist, and the note on ratings. When the context is clear, send the destination and quantity.
Architecture, usable capacity, rated power and the electrical point of connection, written before supplier names are collected.
Systems for the site, plus any pilot, with units that a factory can price without guessing the lot size.
What arrives at the US destination, which accessories travel with it, and which trades remain outside the equipment offer.
Model-specific datasheet, drawing and the compliance files the supplier is prepared to attach to that offer.
State the application, the coupling question you already understand, the quantity and the US destination. The banner explains FREE sourcing support and the up to 3% ceiling for qualified business buyers after review.
